YARN SPINNING 0R TWISTING APPARATUS.

Patented Sept. 9, 1913.

Application filed August 31, 1910. Serial No. 579,921.

To all whom it may concern:

Be it known that I, GIANNI BETTINI, of Paris, Republic of France, have invented a new and useful Improvement in Yarn Spinning or Twisting Apparatus, which improvement is fully set forth in the following specification, reference being had to the accompanying drawing.

The invention has for its object a special arrangement and a new form. of travelers and rings for machines for spinning and twisting the yarn with a view to allowing a much greater speed to be given. to the spindles (hence an increase for the output of the machines), to reducing to a minimum thebreaking of the yarnduring the running of the machines and to obtaining yarns better formed with more regular twist. With this end in view attempts havealready been made to replace fixed ringsinspinning machines by movable rings, revolving with the travelers,"but up to the present none of these rings, which are actuatedonly by the yarn, has given thoroughly satisfactoryre sults. Their principal defect is that those rings which at the outset revolve perfectly, afterward and in a short time develop an irregular rotation. Frequently they even stop altogether by reason of the fluff which fills the atmosphere of the spinning ,factories introducing itself between the rings.

Furthermore a considerable force is re-' quired to rotate these rings which are generally moved by frictional contactwith the traveler which is itself moved by the thread. Consequently the thread frequently breaks. By my device the traveler rotates in part by the pull of the thread and inpart by the movement of an independent traveler carrier which is caused to rotate by frictional contact with some moving part of the spindle. In the preferred form a light balanced traveler carrier is mounted axially by frictional contact on the spindle and in practice rotates at. a speed somewhat slower than the spindle. Furthermore as is well known the thread tension on a spindle varies according to the amount of thread on the bobbin. Bvmy device the tension becomes practically uniform since thethread is delivered by the traveler constantly close to and at the same distance from the bobbin. The thread also passes through an eye or eyes on the traveler carrier or connected with it and then through the eye of the traveler. By this device uniformity of tension and twist is further obtained.

In the annexed drawings which illustrate by way of example methods of executing the invention, similar letters refer to similar parts.

Figure 1 represents in vertical elevation my new device in the form of a rod to give the traveler greater facility of rotation; this I call my traveler carrier. Figs. 2 and 3 represent special forms of the traveler carrier. Fig. 4 represents a form of my traveler;

In order to facilitate the rotation of the traveler, the latter in any form. for example, that represented in vertical section in Fig. 4 is engaged wit-h a rod A Fig. 1) of suitable form capable of revolving on the axes a and 6, corresponding to that of the spindle. A rod thus arranged will be able to revolve with the traveler at very high speeds without fear of wear or danger of the factory dust impeding its motion.

In Fig. 1, A represents the rotating rod or traveler carrier, B the traveler capable of sliding along the rod, C any ring fixed or movable suitably fitted to the carriage of the machine, controlling the rise and fall of the traveler along the rod during working; a is a cap fitted to the top of the bobbin with a bearing to take the upper point of the rod A and to form an axis of rotation; at b the rod terminates in the form of a ring capable of revolving around the foot of the spindle; f represents the yarn and O the bobbin. By this arrangement the traveler B will easily be actuated along with the rod A in its rotation by the yarn assisted by the friction of the spindle on the rod at a and b, thusit will be possible to give much greater speeds to spindles and the stress upon the yarn will be reduced to a minimum.

In order to give the yarn a constantly uniform tension, the arm 11?. bent in any suitable way (or any other extension of the traveler) is made to rest against the bobbin 7 in such a way that the guide eye m is a little farther out from the surface of the bobbin.

As an example of a means for holding the arm m in contact with the bobbin I have shown a spring thread or strand P which is approximately parallel to the rod A, being connected to the u per and lower arms thereof and which bears against the arm m", holding the latter at all times in contact with the bobbin. WVith device of this kind, the tension of the yarn will be kept uniform, the force needed for actuat ns t m el hwin s t e rs the hem The traveler will be able at the same time to slide along the red A. according to the rise and fall of the fraine of the machine carryin h rin by wh h it s uid Th rame i p at d h h sua Way y g an th thread and he tra eler enga s with i as there, er in ar oth t eh h I w uld e e h pess hl ne t m l the es er gu din th aveler, utilizing instead the direct control of the ring carrier fralne.
